            are the
            immediate sources of the annotation herein.
            A consensus sequence for the l-strand of the genome is shown.
            Population heterogeneity as distinct from strain variation is known
            (35937 +/- 9 bp) [67]; both are annotated as 'variation' below. For
            site differences with adenovirus type 5, see loci beginning <ad5>
            which are arranged in the library according to the map coordinates
            of <ad2> where one map unit corresponds to 360 bases throughout
            (see [44],[67]).  For mutational changes in the ad2 sequence, see
            the appropriate references above.
            The origin of replication is located in the first fifty bases from
            each end.
            Transcription is leftward off the l-strand and rightward off the
            r-strand; in the former case, the annotation shows '(c)' for
            complementary strand.  Complex splicing events give rise to perhaps
            fifty or more distinct mRNA transcripts at early, intermediate and
            late times after infection, many of which are still being
            characterized; in particular, some transcripts are known from
            electron microscopy which are not yet characterized at the sequence
            level.  To date nine mRNA start sites (cap sites) have been
            identified, and these define the general units of mRNAs under which
            all known transcripts are classified.
            From the r-strand, the early transcripts are E1a, E1b and E3.  The
            28 kb late transcript called herein 'major late mRNA' comprises
            five families, L1 through L5, of 3' co-terminal mRNAs.  L1, and to
            a lesser extent L2, can be expressed at early and intermediate
            times [34].  Transcripts from this region contain a common
            tripartite leader sequence at their 5' ends: the three segments of
            this leader are encoded at bases 6039-6079, 7101-7172 and
            9634-9723.  At early and intermediate times, an extra leader
            segment, the 'i' leader, is frequently present (bases 7942-8381).
            The IX message, the only unspliced message in ad2, is intermediate,
            and its termination overlaps that for E1b on the same strand and
            that for IVa2, and most likely E2b, on the opposite strand. From
            the l-strand, or the 'comp strand', early expression derives from
            the E2a, E2b and E4 families of mRNAs, although there can be late
            transcription from E2a.  The E2b cap sites, splice sites and
            termination sites have not been determined at the sequence level.
            From electron microscopy there is evidence that the E2b mRNAs may
            originate at the E2a early cap site at 27092 (c) and terminate at
            the poly-A addition site found for the IVa2 mRNA at 4050 (c) [44].
            IVa2 is an intermediate message.  The promoters for these nine
            classes of mRNAs can be localized and characterized to the
            following extent [32]:

            The mRNA responsible for the 13.6K protein encoded at 7968 has not
            been identified.  The VA I and VA II transcripts are unique in that
            they are generated by RNA polymerase III; for a discussion of these
            low molecular weight RNAs-- the modulation of their start points,
            their promoters, their heterogeneity and their similarity to tRNA--
            see [3],[4],[5],[26] and <ad5a2>.
            The proteins known to be encoded from these mRNAs are given in the
            Features table below, though the details of translation and
            processing have not been fully determined.  In cases such as the
            IIIa peptide or the 11K peptide, the exact span of the coding
            awaits elucidation of the mRNA splicing.  Some of these products
            share reading frames and therefore manifest partial homologies. The
            following table summarizes the unidentified reading frames ('URF')
            of 100 or more amino acids:
